Preparation Important Preparation Instructions Prepare VYJUVEK gel at the pharmacy by mixing the VYJUVEK biological suspension into the excipient gel for immediate use. [see Storage and Handling] The VYJUVEK gel prepared at the pharmacy, should be applied by a healthcare professional (HCP), patient, or caregiver either at a healthcare professional setting (e.g., clinic) or at a home setting.

Individuals who are pregnant should not prepare or apply VYJUVEK gel and should avoid direct contact with the treated wounds or dressings from treated wounds [see Accidental Exposure to VYJUVEK]. Below is the list of supplies needed for VYJUVEK gel preparation: One carton containing one VYJUVEK biological suspension vial and one excipient gel vial (Figure 1) Two 18-gauge needles Two to four 1 mL administration syringes One 3 mL preparation syringe Two to four syringe caps Protective gloves 70% isopropyl alcohol pads Biohazard container Labels for administration syringes Virucidal agent for clean-up Follow the steps below for VYJUVEK gel preparation.

PREPARE THE PREPARATION SYRINGE 1. Wash hands and put on protective gloves. 2. Remove both vials from the carton and thaw the VYJUVEK biological suspension vial and the excipient gel vial at room temperature for AT LEAST 20 minutes (Figure 1). Figure 1 Carton containing the VYJUVEK biological suspension vial and excipient gel vial Note: Visually inspect the vials to ensure both are in liquid form and completely thawed.

Excipient gel is more viscous and will take longer to thaw (Figure 2). Figure 2 Timelapse of excipient gel thaw from 0 minutes to 20 minutes Note: Once either the VYJUVEK biological suspension or the excipient gel is thawed, do not refreeze. 3. Invert the VYJUVEK biological suspension vial 4-5 times. Do not invert the excipient gel vial. 4.

Remove the caps from the vials and clean each vial stopper with a 70% isopropyl alcohol pad. Allow them to dry. 5. Aseptically connect an 18-gauge needle to the 3 mL preparation syringe. 6. Remove the needle cap and puncture the VYJUVEK biological suspension vial stopper. 7. Hold the vial at 45 to 90 degrees and withdraw 1 mL of VYJUVEK biological suspension into the preparation syringe (Figure 3). 8.

Remove the preparation syringe (still connected to the needle) containing 1 mL of VYJUVEK biological suspension from the vial. Do NOT engage the safety lock. Figure 3 The removal of 1 mL of biological suspension using the preparation syringe 9. Discard the VYJUVEK biological suspension vial in the biohazard waste. 10. Puncture the clean excipient gel stopper and transfer the VYJUVEK biological suspension into the excipient gel vial (Figure 4).

Figure 4 Transferring VYJUVEK biological suspension to excipient gel vial 11. WITHOUT REMOVING THE NEEDLE from the excipient gel vial, lift the tip of the needle above the liquid (Figure 5)and pull the plunger back to the 1 mL mark (Figure 6) to vent the gel vial following the addition of the 1 mL of suspension. Figure 5 The needle above the liquid without removal of any material Figure 6 Pulling the plunger back to the 1 mL mark to remove air pocket 12.

Remove the preparation syringe with the 1 mL of air and engage the safety lock. 13. Discard the preparation syringe and needle into the biohazard waste. 14. Place a 70% isopropyl alcohol pad on top of the excipient gel stopper and hold it tightly in place. 15.Shake VIGOROUSLY for 10 SECONDS (Figure 7). Figure 7 Manually mixing the excipient gel vial Note: The mixture of VYJUVEK biological suspension and excipient gel is referred to as VYJUVEK gel.

PREPARE THE ADMINISTRATION SYRINGES 16. Aseptically connect an 18-gauge needle to the first 1 mL administration syringe and remove the needle cap. 17. Insert the 18-gauge needle into the excipient vial containing VYJUVEK gel (Figure 8). Figure 8 Needle within VYJUVEK gel prior to withdraw 18. Tilt the vial 45 to 90 degrees and withdraw 0.5 mL of VYJUVEK gel (Figure 9).

Figure 9 Administration syringe withdrawing 0.5 mL of VYJUVEK gel with air pocket visible Note: An air pocket may form near the plunger when extracting VYJUVEK gel. 19. DO NOT REMOVE THE NEEDLE FROM THE VIAL; lift the tip of the needle above the VYJUVEK gel and disconnect the administration syringe containing 0.5 mL of mixed VYJUVEK (Figure 10).

Figure 10 Disconnecting the administration syringe containing VYJUVEK gel with air pocket visible Note: Leave the needle in the excipient gel vial stopper. 20. DO NOT flick the syringe to remove the air pocket. Manipulate the plunger up and down, until all air pockets have been removed (Figure 11) Figure 11 Manipulation of administration syringe plunger to remove air pockets 21.

Cap the administration syringe and set aside (Figure 12). Figure 12 Capped syringe 22. Connect a new 1 mL administration syringe to the needle that remains in the excipient gel vial stopper (with the tip of the needle ABOVE the VYJUVEK gel) (Figure 13). Figure 13 Connecting an administration syringe to the needle within the excipient gel vial stopper 23.

Place the bevel of the needle in the VYJUVEK gel, tilt the vial 45 to 90 degrees and withdraw 0.5 mL of VYJUVEK gel into the administration syringe [see steps 17 and 18: Figure 8 and Figure 9)]. 24. Complete steps 19, 20, and 21 above to disconnect the administration syringe and remove the air pockets, prior to capping the administration syringe (Figure 10, Figure 11, and Figure 12). 25.

Repeat steps 22, 23, and 24 if two additional administration syringes are required (each containing 0.5 mL of VYJUVEK gel). Note: Administration syringes are labeled as syringe #1, #2, #3, and #4. 26. Discard the excipient gel vial (with the needle within the vial stopper) into the biohazard container. 27. Clean all surfaces that may have come in contact with VYJUVEK biological suspension or gel and treat all spills with a virucidal agent such as 70% isopropyl alcohol, 6% hydrogen peroxide, or <0.4% ammonium chloride.

Blot using absorbent materials. 28. Dispose all materials (e.g., vial, syringe, needle, cleaning materials) that may have come in contact with VYJUVEK biological suspension or gel into a biohazard container. 29. Place the capped administration syringes containing the VYJUVEK gel in a sealable plastic bag. 30. Place the sealable plastic bag with administration syringes into an appropriate insulated or temperature regulated secondary container at 2° to 8°C (35.6° to 46.4°F) for transport from the preparation site to the administration site. fig1 fig2 fig3 fig4 fig5 fig6 fig7 fig8 fig9 fig10 fig11 fig12 fig13

Administration Below is the list of supplies needed for VYJUVEK gel administration: The administration syringes Hydrophobic dressing Scissors Standard dressing Protective gloves Biohazard container Virucidal agent for clean-up VYJUVEK GEL ADMINISTRATION Note: The administration syringe should be primed prior to the initial application by pulling the plunger down and pushing it upwards, so that a small droplet of VYJUVEK gel forms at the tip of the syringe.

Follow the steps below for VYJUVEK gel administration. 1. Apply VYJUVEK gel to the selected wound(s) in droplets spaced evenly within the wound, approximately 1cm-by-1cm apart (width of a fingertip). The resulting droplet pattern should loosely resemble a grid. Avoid touching the administration syringe to the skin and/or wound (Figure 14).
